What's going on here????http://au.news.yahoo.com/video/sa/watch/92874e80-8223-32f9-a458-bfbb951acafa/big-machines-tackle-seagrass-at-glenelg/http://www.epa.sa.gov.au/xstd_files/Water/Report/seagrass.pdf

JM,I used to live at Port Victoria as a kid and every year beginning in Autumn there would be seaweed like this. And the bay is far more protected than at Glenelg. In fact there are lots of spots in the state where the seaweed isn't gone until Dec/Jan. It needs to dry out and with a decent tide it floats out. We probably just don't see it so much because of the amounts of seagrass lost. I know every year it does drift North and builds up in the vicinity of North Haven, OH Breakwater etc.

You know what i like about SH,its the fact you can write all the crap you want,take the piss or choose to respond in a childish and ignorant manner and after you sift through all of that you might still end up with some.. pearls of wisdom cheers brenton

I was hoping to read a two page report from a person who has a biological background but the ones doing most of the writing are the ones claimed to be simpletons... This is despite Ranger's invitation... OH well, I'm a psychologist and I refuse to bog you down with a 5 page report on my understanding of this matter. I'll just say that you're stubborn.

Thanks TacklesNow you have me worked out !

I have had the benefit of meeting you on a couple of occasions face to face before so I have not had 'as much' to work out as some others on here perhaps?Enjoy your barra fishing.

Hi TacklebagsThanks for your enquiry regarding artificial reefs:• Fisheries promoted and provided tyre module artificial reefs in the 1970’s and 80’s.• Since 1993, Fisheries has taken the conservative approach and discouraged the construction of any additional artificial reefs in State waters.• FRDC recently funded a review of artificial reefs in Australia, and Guidelines for their use have been developed as part of this project http://www.frdc.com.au/research/Documents/Final_reports/2010-400-DLD.pdf• Other states have artificial reef programs, but all recent deployments have all been undertaken with full environmental assessment and monitoring programs that are associated with them• In Australia there is a still a division within the science community as to whether these actually work to increase fish production or just make the fish easier to target, and this varies with the conditions of the habitat/water that the reef is put in, and the size of the reef• Artificial reefs have been talked about recently as potential offsets due to cumulative access loss for recreational and commercial fishers• RecFish SA support the use of artificial reefs, but do not support indiscriminate marine dumpingGiven the conditions that you have indicated in your post above (funding and science), PIRSA is open to investigating the costs and benefits (ecological, social and economic) of establishing artificial reefs.RegardsKeith Rowling | Program Leader, Community Based FisheriesPIRSA Fisheries and Aquaculture

Thanks Keith for the reply and FRDC report. I will keep that one for future reference.

Given the conditions that you have indicated in your post above (funding and science), PIRSA is open to investigating the costs and benefits (ecological, social and economic) of establishing artificial reefs.

That is good to hear. I would hope that with the aid of scientists, AR's designed to compliment/regenerate the exisiting marine environment (not detrimentally change it) for the benefit of marine life and all stakeholders not just fishers, would be attractive to government.CheersTB

Don't need to do too much work Keith, all the science has already been done in the other four major states ( you have know that for many years ),just need to give anglers a break and change the policy which contradicts every other state.
